The heart of our 2 meter 1K2 is a SINGLE very rugged LDMOS FET, rated at 1250 Watts of output! This device is rated to handle 65:1 mismatch! the amp monitors device temperature and current, VSWR, drive and mode to adjust output. Designed by Ken Holladay, K6HCP (KLM, Mirage and RF Concepts, now JK RF Designs), the 1K2 amplifier is beautiful in it's simplicity. The 13 pound 1K2 is the smallest 1200W amplifier ever offered.
Weak-signal communications, particularly at VHF and above, sometimes require performance that cannot be delivered by a transceiver alone. Often, a low noise preamplifier (LNA), a power amplifier (PA) and sometimes a transverter are needed to afford the extra edge necessary for terrestrial, Earth-Moon-Earth (EME) and satellite communications. It is vital to provide extra transmit-receive (T/R) isolation and switching with enough time delay to ensure that an ill-timed burst of power doesn’t destroy sensitive equipment. A sequencer is the “brains” of a weak-signal station. The S3 Sequencer provides the timing and switching necessary to run most terrestrial and EME stations, without adding a lot of weight and expense. Inspired by its big brother, the S2 EME Sequencer, this is perfect for the anyone who wants high-performance features at low cost. Its small size and easy setup make it IDEAL for trips and portable operation. VHF/UHF contesters will find it especially useful for rover setups, where several can be stacked in a small area, drawing little power yet providing complete control of outboard equipment. Pair this with one of our new preamps or power amplifiers and be a “Big Gun” for small change!
The 10-15M1DX is a single-band dipole antenna designed with performance and affordability in mind without skimping on quality. Originally designed by radio pioneer Heinrich Hertz in 1886, the dipole antenna was originally called the “Hertz” antenna. It stands the test of time as the basis of most high performance antennas today. Built to the demanding specs of our “DX” series yagis, this antenna uses 6061-T6 aluminum tubing and 6061-T6 aluminum machined hardware for its durable, lightweight elements. A solid fiberglass center insulator, machined aluminum mast mounting components and stainless steel hardware will keep this in the air for years. Versatility is key for this antenna—equally suited as a fixed or rotatable dipole. Lightweight and low-profile, it’s the perfect HF antenna for your QTH, whether you want a simple, unobtrusive, no-compromise radiator on a tower or mast, or in a stealthier application such as in an attic. “Uni-cradle” mounting allows it to securely grip a wide range of masts. With element sections of 48 inches (122 cm) or less in length, its light, simple and compact design makes it an ideal candidate for Field Day, SOTA, DXpeditions and EMCOM use. It can easily be configured and reconfigured for any frequency from 20-30 MHz simply by changing the tip length. Have a custom application that you would like to try? Use it as the basis for your own high-performance, innovative antenna projects.
